Ofcom has published a revised UK Frequency Allocation Table which can be found here. This details how various frequency bands are used in the UK, and which bodies are responsible for planning and managing them – including frequencies assigned to individual users or installations at particular locations. It also shows the internationally agreed spectrum allocations of the International Telecommunication Union.
Ofcom has also developed a revised rain map which can be found here based on analysis of rainfall records for all of the UK. This can be used by Ofcom to assess likely rainfall in a given location when planning wireless fixed links, as rainfall intensity may influence the quality of transmission achievable between two points.
